The cercariae are weak swimmers and are blown about by the wind. Swim in areas with an off-shore breeze.Near shore is where the cercariae tend to concentrate. Swim in deeper waters, not the shallow areas near shore.

If cercariae are on the skin they will try to penetrate the moment you emerge from the water. Rub down briskly with a towel when emerging from the water.Apply a water repellant substance such as petroleum jelly, waterproof sunscreen or other skin oils to reduce the ability of the Cercariae from penetrating the skin.The only sure way to prevent Swimmer's Itch is to stay out of the water when the cercariae are present, but the following can reduce the chances of contacting Swimmer's Itch. Humans are not a suitable host and the cercariae die after penetrating the skin. The skin is penetrated and if a suitable host is found the life cycle starts all over again. The Cercariae find a host (aquatic birds, mammals or humans).

A baking soda bath can be made by combining a half cup to one cup of baking soda into a tub full of water. Baking soda helps to reduce inflammation, thus providing soothing relief. The itch individuals experience is typically due to inflamed skin. The miracidia penetrate snails and further develop into cercariae, minute free-swimming, fork-tailed colorless animals that are then released by the snails. Individuals with swimmers itch may find some relief if they take warm baths with baking soda.

The eggs hatch and free swimming animals called miracidia are released into the lake water.

The eggs are deposited on the bottom of the lake through droppings.

The adult worms are parasites in the blood of aquatic birds and mammals.

Itching can be mild to severe and can last several days.ĭucks are the most common host of the worm but other birds and mammals that spend their life in or around the water may also be a host. Small red dots appear at the site of penetration. As penetration occurs a prickly, or itching sensation occurs followed by gereral inflammation of the affected area. Cercariae penetrate the skin of bathers as water droplets dry. Once a case is reported and verified, warning posters are posted at the site to inform swimmers and beach comers of the potential risk and precautions they should take.Įmerging Infectious Diseases: “Cercarial Dermatitis Transmitted by Exotic Marine Snail” Brant et al.Swimmers itch (Schistosome dermatitis) is a temporary skin infection acquired by bathers in some lakes when they accidentally become involved in the life cycle of the trematode worm. Presently, there is a “Beach Water/Swimmer’s Itch Hotline” (510.567.6706) to enable the public to report swimmer’s itch cases. This collaborative effort resulted in a publication that summarized the current biology and classification of this parasite. This snail was first reported in San Francisco Bay in 1999. The swimmer’s itch was caused by a previously unknown microscopic parasite that was shed by a newly invasive snail-the Japanese bubble snail. From 2005 to 2008, our District collaborated with the University of New Mexico in identifying the new parasite. In 2004, cases of swimmer’s itch among beach visitors at Robert Crown Memorial Beach in Alameda were subsequently found to be caused by an invasive, previously un-described marine parasite. Cercarial dermatitis (swimmer’s itch) is caused by the penetration of human skin by cercariae (larva) of schistosome parasites that develop in and are released from snail hosts.
